Black smoke usually indicates car is burning to much gasoline. Which would account for the O2 light coming on.

My idea - I have found a couple of f150 trucks with clogged cats. most on the left side but there is a back pressure test that you can do with the o2 sensors removed. note ( one of the trucks acted up on rare occasions but when it finally acted up for me I knew what it was instantly. Good luck.
